Abstract

PURPOSE:To make the heat exchanger compact by a method wherein in the case a device such as a CRT display device which generates heat itself, a fin is inclined forward and rearward or right and left and fans are housed within spaces provided between the wall surfaces of the heat exchanger and the fin due to the inclination of the fin. CONSTITUTION:The corrugated fin 11 is slightly inclined forward and rearward or right and left and the fans F and F' are arranged in the spaces provided at both inclined ends of the corrugated fin 11. In this case, no side plate is fixed to the inclined surface of the corrugated fin 11 but only passages for air (a) and air (b) are formed between the outer walls 14 and 15 of the heat excahnger and the surfaces of the fin 11, respectively. The air (a) supplied by the fan F flows along one of the surfaces of the fin 11 and flows out from an air outlet port 12 while the air (b) supplied by the fan F' flows along the other surface of the fin 11 and flows out from an air outlet port 13.

[B and both sides of the wave-shaped fin 1, as shown in the cross-sectional view of FIG.
It is closed with side plates 4 and 5, leaving behind. The air outflow ports 2 and 3 are provided on opposite sides of both ends of the corrugated fin 1, and also on both sides of the corrugated fin 10 and on the sides 6 and 7 of the side plate 4.
5 and the wavy fins 1 are alternately closed. Therefore, the air a sent by the fan F flows out of the heat exchanger through the air outlet 2 through the space formed by the side plate 4 and the corrugated fins 1, as shown in Fig. 2. . Further, the air sent by the fan F' passes through the space formed by the side plate 5 and the corrugated fins 1, and is discharged to the outside of the heat exchanger through the air outlet [13]. As a result, while the air a, t]' flows through the corrugated fin 1, heat is exchanged between the air a and b' via the corrugated fin 1, and the hot air is cooled and heat is radiated. A heat exchanger of the type shown in FIG. This heat exchanger is different from the heat exchanger shown in FIG. 1 in that the heat exchanger 2' is provided on both end sides of the corrugated fins 1, but the operation is almost the same as that shown in FIG. Among the conventional heat exchangers described above, the heat exchanger of the type shown in FIG. Even if F' is small, its length will be longer by the amount of fan [, F'. In addition, the type of heat exchanger shown in Fig. 3 has fans F, F'
are provided on the sides of the fins 1, so the length can be reduced, but the thickness is increased, making it difficult to make a compact heat exchanger. Also, if the air reservoir part 8.9 installed between )7 fans F and F' and fin 1 is made smaller, the horsepower of the fan will be increased and the air will have to be sent under a large pressure, so the size will be increased to a certain extent. As a result, it was not possible to form a heat exchanger in the compact 1. Furthermore, the heat exchange of conventional heat exchangers is
As shown in FIG. 2, the process is not performed on the entire surface of the corrugated fin 1, but only on the fin side C portion of the flow path of each air a, 1], and the surface in contact with the side plate 4.5. However, the area of the fins used for heat exchange was small and the efficiency was not good. Therefore, an object of the present invention is to improve the above-mentioned drawbacks of the conventional heat exchanger and to provide a compact and efficient heat exchanger. An embodiment of the present invention will be described below with reference to the drawings. FIG. 4 is a side cross-sectional view of one embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along the line B-B in FIG. is the point (a) where the corrugated fins 11 are attached with a slight inclination in the front and rear or left and right directions. Fans F and F' are provided in spaces at both end side surfaces of the wave-shaped fins 11, which are formed by the inclination J:. As shown in FIG. 5, no side plate is fixed to the side surface of the corrugated fin 11, and the side plate is simply attached to the outside 21/I, 1 of the heat exchanger.
Only air passages a and b are formed on one side of the fins 5 and 11. Further, the end surfaces 16 and 17 of the corrugated fin 11 may be completely closed, but only the side where the air passage is formed may be opened. That is, as explained in the conventional example shown in FIG. 1, it is sufficient to open the gates alternately. In the above configuration, the air a fed by the fan F' flows over one surface of the corrugated fin 11, flows out from the air outlet 12, and the air a fed by the fan F' flows over one surface of the corrugated fin 11.
flows on the other surface of the corrugated fin 11, and air outflow q 1
3 J: Flow out. As a result, the air a and the air exchange heat through the entire surface of the corrugated fins 11. As described above, in the heat exchanger of the present invention, the fins are inclined forward and backward or left and right, and the fan is housed in the space created by the inclination. It can take a large amount, and also,
Since no ducts are required, air resistance can be reduced, and there is no need to increase fan capacity. In addition, since the side plate is not fixed to the side of the fin and the air passage is formed by the side of the fin and the outer wall of the heat exchanger, the heat dissipation area of the fin becomes the entire surface of the fin, increasing the heat dissipation area. Heat exchange efficiency can be improved. Furthermore, since the air passage is formed to become narrower toward the air circulation opening, the air flows on the surface of the fin and the outflow wind speed from the air outlet increases.
This improves convection inside and outside the device and enhances the heat dissipation effect.
